I've done some testing and the calculation for number of criminals in the population is off.
My nation has 55109 population (with all of my criminals rehabilitated, so this should be my pre criminals population). I have Crime Index 0, so I should have 0.5% of that number rehabilitated.
55109 * .005 = 275.54 ~ 276
My nation says I only have 273 criminals rehabilitated. This means I either have 3 criminals MIA, or one of these options is occurring:
Criminal Population is calculated against some other, lower number (which is unlikely as I can calculate my population to be 55109 using my vital statistics)
The multiplication % is not exactly 0.5% fro CI 0
something else that I can't think of right now
